ICP 1-Pole 30A Contactor for WJH330000KTP0A1 — 24V Coil with Shunt | Ships Today

Overview

This is the genuine OEM 1-pole 30 amp contactor with shunt (part #1172472) and a 24V coil for ICP, Tempstar, and Heil units. The contactor is the electrically operated switch that delivers high-voltage power to the compressor and condenser fan whenever the thermostat sends a 24V call to the coil. The built-in shunt maintains a circuit path on the unswitched leg. Contactors are high-cycle wear items — the contacts pit, burn, and weld over time, and the coil can fail open. A bad contactor causes a unit that won't start, chatters, or won't shut off.
